DEVICE FOR HANDLING INGOTS.

SPECIFICATION forming part of Letters Patent No. 440,219, dated November11, 1890.

Application filed May 13,1890. Serial No. 351,609. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS BRADY, a citi zen of the United States,residing at South Chicago, in the county of Cook and State of Illinois,have invented a new and useful Device for Handling In gots, of which thefollowing is a specification.

This invention relates to devices for handling ingots in the process ofmanufacturing steel; and it has for its objectto provide mechanismwhereby the ingots may be handled more conveniently and rapidly thanheretofore.

The invention consists in the improved construction, arrangement, andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims.

Heretofore in the manufacture of steel it has been customary to set themolds in a pit in the converting-mill to receive the molten metal fromthe ladle. After casting the ingots they have been stripped of the moldsand loaded upon a special car to be transferred to the rolling-mill.This has been a laborious process, and it has been attended with thedisadvantage that the ingots have been exposed to the air before beingcharged into the furnaces, thereby frequently causing the surfaces ofthe ingots to become cracked.

My invention has for its object to avoid, as nearly as possible themanual handling of the ingots, and this I accomplish, first, by mountingthe molds or flasks upon a specially-constructed car, in which the moldsremain while the molten metal is being poured into them, said car beingprovided with a pivoted frame, in which the said molds are mounted;secondly, in providing a pushing device by means of which the. ingotsmay be pushed from the molds into the furnace, said pushing device beingso constructed and arranged as to be capable of serving two or morefurnaces.

My invention resides more particularly in the detailed construction ofthe said car and pushing mechanism, in the mechanism for adjusting andoperating the latter, and in such other details of construction whichwill be portion of a steel-manufacturing plant, comprising the furnaces,the ingot-pushing mechanism, and the mold-carrying car, showing therelative arrangement of the several parts. Fig. 2 is a side elevation ofthe ingot-pushing mechanism, showing the pusher-cylinder arranged inposition for operation and looking toward the front end of saidcylinder. Fig. 8 is a vertical sectional view taken on the line 3 3 inFig. 2, and showing the pusher cylinder in side elevation and the carupon which it is mounted in end view. Fig. 4 is a sectional view takenlongitudinally through the pusher-cylinder and transversely through thecar. Fig. 5 is a sectional view taken longitudinally through the frameof the push mechanism on the line 5 5 in Fig. Fig. 6 is a perspectivedetail view of the pushercylinder and adjacent parts. Fig. 7 is an endelevation of the frame in which the pusher mechanism is mounted. Fig. 8is a detail view, 011 an enlarged scale, of the front end of thepusher-cylinder. Fig. 9 is a side elevation of the mold-carrying carwith the molds in position upon the same. Fig. 10 is a longitudinalsectional view of the said car. Fig. 11 is a transverse sectional viewof the same. Fig. 12 is a perspective view of one end of the said carhaving the adj usting-worm and spur-wheel. Fig. 13 is a sectional viewof the furnace, mold-carrying car, and pusherframe, showing thepusher-cylinder partly in elevation and showing the several parts inposition for operation. Fig. 1a is a perspective detail view of theinner side of one end of the mold-carrying car. Fig. 15 is a detail viewof one of the supports for the bottom of the molds. Fig.10 is a frontview of the furnace. Fig. 17 is a longitudinal sectional view of thefurnace. Fig. 18 is a perspective view of one of the peels.

Like numerals of reference indicate like parts in all the figures.

1 designates the base-plate, which is mounted upon a very substantialfoundation of masonry, and which is provided on its upper side withlongitudinal track-beams 2 2, which may be cast or formed integrallywith the base-plate. Rack-bars 3 are formed upon the outer sides of thesaid track-beams.

At the ends of the base-plate 1 are mounted the vertical upright platesor standards 4: 4,

the upper ends of which are connected by the longitudinal track-beams 55, which, as shown in the drawings, will be 'L-shaped or composed ofplates having upwardly-extending flanges at their outer edges.

6 designates a car which is mounted to ride upon the longitudinaltrack-beams 2. Said car consists of the platform 7, which is mountedupon the trucks 8 8. The platform is provid ed with downwardly-extending arms 9, supporting a plate 10, that forms a slide fitting between thetrack-beams 2 2. The wheels 11 of the car 6 are provided withspur-wheels 12, that engage the longitudinal rack -bars 3, therebypreventing the wheels from dragging 0r sliding upon the track-beams. Theslideplate 10 serves to prevent lateral displacement of the parts in thedevice when in operation, as will be hereinafter described.

'13 designates a mast which is mounted pivotally upon the platform ofthe car. The upper end of said mast is likewise mounted pivotally in acar or carriage 14, which is mounted to ride upon the upper longitudinaltrackbeams of the frame.

The car or carriage 14 is provided with wheels or rollers that ride uponthe trackbeams, and it has on the under side a slideplate 15, that fitsbetween said track-beams and prevents the car from being laterallydisplaced.

The car or carriage 6 is provided with a lug 16, having a notch 17,adapted to be en- 7 gaged by a lever or catch 18, which is pivotallyattached to the mast, which latter may thus be locked in position foroperation.

The car-platform is provided with a notched lug at each end, with eitherof which the locking-lever may be placed in engagement.

The mast 13 carries the horizontally-arranged pusher-cylinder, both endsof which are connected with the mast near the upper end of the latter bymeans of inclined guys or braces 19. The cylinder, which is designatedby 20, has the longitudinally-movable pistonrodf21, which is providedwith a suitably-located piston 22. The front end of the pistonrodextends through a packing-box 23 at the front end of the cylinder.

24 designates a head which is mounted detachably at the front end of thepiston-rod.

Said head, which is cylindrical in shape, is provided with alongitudinal perforation 25,

by means of which it is mounted slidingly upon the piston-rod, and ithas atits rear end a staple or perforated lug 26, through which a key orpin 27 passes into a perforation in the piston-rod, upon which the saidhead may thus be locked. The front end of the pistonrod is aeo providedwith a perforation 28 o receive the hook at the end of the drawing-Kongs when the device is to be used for drawing the ingots from thefurnace, as will be hereinafter described.

The front end of the pusher cylinder is provided with aforwardly-extending U-shaped bail or bracket 29, having a perforation 30for the passage of the piston-rod. The object of this is to support orpartially support the weight of the front end of the piston-rod and torelieve the packing-box 23 of such weight, thereby preventing injury tosaid packingbox and avoiding the leakage which would otherwise in timeresult from such strain or wear.

The upper and lower sides of the cylinder are provided with brackets 31,having bearings for a pair of longitudinally-sliding rods 32, which rodsalso extend through transverse openings 33 in the mast or derrick.

Pivotally connected to the front ends of the sliding rods 32 are thegrappling-arms 34, the front ends of which are provided with hooks 35,adapted to engage perforated lugs or staples at the upper ends of themolds, as will be hereinafter described. Connected pivotally to one sideof the cylinder is a lever 36, having a handle 37, by means of which itmay be conveniently manipulated. The ends of said lever are providedwith swiveled eyes 38, encircling the grappling-arms 34 and serving whenthe lever is manipulated to bring the outer or free ends of saidgrappling-arms together or apart, as may be desired.

39 designates a table or platform which is secured near the lower end ofthe mast or derrick at one side of the pusher-cylinder. This platform isfor the accommodation of the operator whose duty it is to attend to themanipulation of the lever-handle 37 and other parts of thepusher-cylinder, which are to be hereinafter described.

40 designates a clutch member which is mounted to slide longitudinallyupon the cylinder, and which is provided with perforated lugs orbrackets 41 for the passage of the longitudinal rods 32, which aresecured in said brackets. Springs 42 are coiled upon the rods 32 betweenthe brackets 41 and 31 and serve to force the clutch member 40 and therods 32 normally in a forward direction. A clutch member 43 is arrangedrevolubly upon the cylinder between the clutch member 40 and the mast.The clutch member 43 is provided with a handle 44, by means of which itmay be manipulated to force the clutch member 40 in a rearwarddirection. This is for the purpose of drawing the molds containing theingots up against the head at the front end of the piston-rod when thedevice is to be operated for pushing the ingots out of the molds, aswill be hereinafter described, thereby relieving the mast and otherparts of the machine of excessive and unequal strain, which might proveinjurious.

The piston-rod in the pushercylinder is operated by hydraulic power, thewater being supplied under pressure to the ends of the cylinder throughpipes which are designated by 45 and 46. Both of these supply-pipes areconnected with a valve-casing 47, containing an ordinary four-way valve48. Suitably connected with said valve-casing are also the supply-pipe49 and the exhaust or discharge IIO pipe 50, the latter extendingthrough a vertical perforation in the lower end of the mast. The valveitself forms no part of my present invention, it being simply soconstructed that the supply may be connected with either end of thecylinder, while the exhaust is connected with the other end, or that thesupply and the exhaust may both be cut off at will. The supply-pipe 49extends from the valve-casing up alongside the mast 13 and through anopening 51 in the side of the latter, and thence in an upward directionthrough the top of the mast and through the car or carriage 14, abovewhich the said supply-pipe 49 is connected with a swivel-jointed pipe52, composed of any desired number of sections having their meeting endsconnected by swivel-joints, so as to admit of said swivel-jointed pipebeing extended or contracted, according to the position of the carcarrying the pusher-cylinder. The end of the swivel-jointed pipe 52 isconnected with the main supply-pipe 53, which is mounted adjacent to oneof the end plates 4 of the frame. A pair of longitudinal trackrods 54,having their ends attached to the upper ends of the end plates 4 of theframe, serve to support the swivel-jointed supplypipe.

The cars carrying the pusher-cylinder and its attachments are operatedor carried along their respective tracks by means of mechanism, asfollows:

55 designates a hydraulic cylinder, which is arranged alongside of oneof the trackbeams 2 upon the base-plate, and which is provided with apiston -rod 56, extending through packing-boxes 57 at both ends of thecylinder. The piston-rod 56 has a centrallylocated piston 58. Pipes 59and 60, for supplying water under pressure, are connected with the endsof the cylinder and with the casing 61 of a four-way valve 62,which isalso connected with the main supply and discharge pipes 63 and 64 insuch a manner that water may be supplied to either end of the cylinderwhile it is being discharged from the opposite end, or that both thesupply and discharge may be simultaneously out oif. The valve 62 isoperated by means of a lever or handle 65. To the ends of the piston-rod56 are attached the brackets 66, each of which is provided with bearingsfor two pulleys 67 and 68. Guide-pulleys 69 and 70 are suitably arrangednear each end of the bed-frame. The frameplates 4 are provided neartheir lower ends with perforations 71, adjacent to which guidepulleys 72are arranged, and similar guidepulleys 73 are arranged near the upperend of each of said bed-plates 4. To the bearingframe of each of theguide-pulleys 69 is attached a wire cable 74, which passes over thepulley 67 at the adjacent end of the pistonrod 56, thence under theguide pulley 69, thence over the guide-pulley 72 and through theperforation 71, and to the adjacent end of the car or carriage 6, whereit is securely attached in any convenient manner. To the bearing-frameof each of the pulleys 7 O is attached a similar wire cable 75, whichpasses over the guide-pulley 68 at the adjacent end of the piston-rod56, thence under the guidepulley 70, and over the guide-pulley 13 to theadjacent end of the car or carriage .14, to which it is suitablyattached.

It will be seen that by the foregoing arrangement of parts when thepiston-rod 56 is caused to move in either direction the cars orcarriages 6 and 14, supporting the mast 13, with the pusher-cylinder andall its attachments, will be moved in the opposite direction. It willalso be seen that the upper and lower cars are moved at precisely thesame rate of speed, thereby preventing the possibility of any of theparts of the machine getting out of alignment. It may here be statedthat the lower car 6 is to be provided with suitable brake mechanism175, the special construction of which, however, is not considered apart of my present invention. This brake mechanism is considereddesirable for the purpose of effectually preventing any possibility ofthe machinery being displaced while in operation, and it will be seenthat such brake mechanism, serving to lock the wheels of the car, havingspur-wheels intermeshing with the rack-bars upon the longitudinaltrack-beams,will effectually and positively prevent longitudinaldisplacemet of the car,while its lateral displacementis quite asefficiently prevented by the arrangement between the longitudinaltrack-beams of the slide-plate 10, which forms a part of the carstructure.

The piston-rod 56 is provided near each end with an upwardly-extendingyoke or bail 77, which rides upon guide-rods 78, which are suitablyattached at the ends of the cylinder to the frame-plates 4 at the endsof the frame structure. By this means the weight of the ends of thepiston-rod carrying the pulleyframes 66 is taken ofi the packing-boxesat the end of the cylinder, the advantages of which will be readilyunderstood.

The parts of my invention thus far de scribed, and which constitute themechanism for pushing the ingots from the molds into the furnaces andfor drawing the ingots from the furnaces may be operated by twoattendants, one of whom is stationed at the valve-lever 65, controllingthe mechanism for causing the cars to travel in either direction, andtheother of whom is stationed upon the table or platform 39, whereby theymay conveniently manipulate the lever-handle 37, whereby thegrappling-rods 34 are actuated, the lever-handle 44, by means of whichthe clutch member 43 is operated, and a leverhandle 79, which issuitably connected by means of links and connecting-rods with the stemof the valve 48, which latter may thus be maniulated so as to cause thepiston-rod to be operated in either direction.

The ingot pushing and drawing mechan ism, which has been described inthe foregoing, is in practice to be arranged longitudinally between twofurnaces, which may be of any suitable construction and dimensions. Iprefer this arrangement, for the reason that owing to the fact that themast or derrick carrying the pusher-cylinder is swiveled in the mannerdescribed,it maybe employed to serve two furnaces or sets of furnaces aswell as one. Consequently a considerable economy in the initial cost ofthe plant may be eifected by arranging the pushing and drawing mechanismto serve two furnaces, one on each side, as described.

I shall now proceed to describe the structure of the car carrying theingot-molds, in which the ingots are transported from theconverting-mill and to the furnaces. I desire in this connection. tocall attention to the patentgranted to me in the United States on the15th day of October, 1889, No. 412,832, for improvements in devices forcasting ingots. This device is the one which it is intended to use in,connection with my present invention, and it provides for the casting orpouring of the molten metal from the ladle directly into, the molds,which are described as being supported upon suitable cars. The specialstructure of'said cars, however, I purposely omitted to show or describein the Letters Patent above referred, for the reason that the saidcar-structure is more properly a part of the present invention.

.1 make the foregoing statement merely to show that I have providedmeans whereby the ingots may be cast in molds supported upon a travelingcar structure.

Arranged or constructed alongside the bedplate 1 and parallel to thetrack-beams 2 on said bed-plate are the tracks 80, which extend at oneend to the frames upon which the ladles are supported while castingingots and at the other end to the rolling-mills. Thesaid tracks arearranged intermediately between the base-plate 1 and the furnaces,whichlatter are designated by 81.

The mold-supporting car is composed of the longitudinal frame piecesorsills 82, supported upon the wheels 83 and supporting the heavyvertical end frames 84. The latter are provided with bearings 85, oflarge diameter, for the trunnion-plates 86, between which and thebearings the friction-rollers 87 are interposed for the purpose ofenabling the moldcarrying frame to be conveniently manipulated andadjusted to its proper position. The trunnion-plates and the anti-friction rollers are retained in the bearings by means of the annularflange-plates 88, which are suitably secured to the outer and innersides of the trunnion-plates.

The mold-carrying frame is composed of two heavy side pieces or girders89, which are provided on their inner sides with flanges 90 'to supportthe molds when the latter are in a horizontal position and on theirouter sides with longitudinal strengthening-ribs 91 and 92, formed,respectively, at their upper and lower edges and longitudinally alongthe center. The side pieces or girders 89 are cast hollow, in order toadmit of their being filled or charged with water for the purpose ofpreventing the heat from the ingots from warping or otherwise injuringthem. The ends of the girders are 4 provided with flanges 93, adapted toengage supporting-cleats 94 upon the inner sides of the trunnion-plates.The

side pieces or girders are secured firmly in the said supporting-cleatsby means of keys 95, driven into the said cleats alongside of theflanges 93. The inner sides of the side pieces or girders are providedwith vertical supporting-cleats 96 to receive flanges 97, formed at theends of transverse brace-plates 98, by means of which the said sidepieces or girders are securely connected. It will be observed that bythis construction and arrangement the parts constituting themoldcarrying frame may be very conveniently and securely put together ortaken apart for repairs, while at the same time great strength andfirmness of the various component parts are attained, which is obviouslyimportant,

vowing to the heavy weight which has to be sustained and thecircumstances under which the ingots are to be handled.

The molds or flasks, which are designated by 99, are in the main ofordinary construction, but are provided with laterally-extend ingsupporting plates or flanges 100, that extend through the vertical slotsor port-holes 101, which are formed in the side pieces or girders 89directly above the central strengthening-ribs 92 of the latter. Theslots 101, it will be seen, will admit of a limited movement of themolds or flask 99 in the direction of the length of the latter. Saidmolds or flasks are provided at their upper edges with perforated lugsor staples 102, adapted to be engaged by the grappling-rods 34 of thepushing mechanism, which has been hereinbefore described.

In the drawings hereto annexed I have shown the mold-carrying frame assupport ing a series of four molds; but it is obvious that a greater orless number of molds may be used when desired. The molds are open attheir lower ends, and the bottoms for the said molds consist of a seriesof blocks 103, mounted upon-or formed integrally with a plate 104, whichis provided with an annular upwardly-extending flange 105,surroundingthe individual mold-bottoms. Thebottom plate 104 is provided on itsupper side near its ends with perforated lugs or staples 106, by meansof which said bottom plate may be suspended under the molds in such amanner as to be capable of being disengaged from the latter for thepurpose of enabling the ingots to be pushed out after the molds havebeen adjusted to an approximately-horizontal position.

The trunnion-plates 86 at the ends of the car are provided with radialslots 107, in which are mounted the supporting devices for the bottomplate of the molds. Each of said supporting devices comprises a shaft108, extending through the slot 107 and having at its inner end adownwardly-extending arm 109,

provided at its lower end with a hook 110.

The outer end of each of the shafts 108 is p"ovided with an arm 111.

Connected pivotally to the outer side of each of the trunnion-plates 86at a point near the upper end of the slot 107 is an arm or lever 112,having an eccentric-ring 113,through which the outer end of the shaft108, having the arm 111, extends. The eccentric-rings 113 are providednear the fulcra of the levers 112 with notches 114. It will be seen thatby manipulating the said levers the shafts 108 may be raised or liftedupwardly in the slots 107, thereby lifting the mold-bottom,which hasbeen previously mounted by its lugs or staples 106 upon the hooks 110 upinto contact with the lower ends of the molds. The mold-bottom may beretained in this position by placing the ends of the operating-levers112 under studs 115, attached to the trunnionplates.

It will be seen that the mechanism for adjusting the mold-bottom iswholly connected with the trunnion-plates. Hence the latter may beturned so as to adjust the molds to any desired position withoutchanging the position of the mold-bottom, which is important, forreasons which will be hereinafter made apparent.

The trunnion-plate S6, at one end of the car, is provided with a bracket116, to which is attached a segmental gear or rack 117, which isconcentric with the upper half of the trunnion-plate. Brackets 118,secured to the upper end of the end plate 84, are provided with bearingsfor a shaft 119, provided with a worm 120, engaging the segmental rack117. The shaft 1 .9 has a square end 121, upon which a crank 122 may beplaced for the purpose of manipulating said shaft. It will be seen thatby this mechanism the trunnionplates and the mold-carrying frame may beswung or tilted in an arc of one hundred and eighty degrees, thusenabling the molds to be tilted to either side into a horizontalposition.

It is obvious that the parts of the mold-carrying car and the pushingmechanism are to be so proportioned with relation to each other that themolds when occupying a horizontal position shall be practically inhorizontal alignment with the piston-rod of the pushercylinder.

The furnaces 81 are arranged, as above described, alongside of thetracks 80 and parallel to and at a suitable distance from the frames ofthe ingot pushing and drawing mechanism. The said furnaces'are in themain of ordinary constructiona suitable number of charging-doors 123,which are located a suitable distance apart, so as to enable two ingotsto be charged through each one of the doors, means being provided, aswill be presently described, for tilting the ingot, which is firstcharged to either side of the charging-door, so as to leave room for thenext one. For the purpose of thus tilting the ingots out of alignment-With the chargingdoors, I avail myself of the peels 1.24:, each of whichconsists of a plate of suitable dimensions having slightly upturned orcurved side edges 125 and provided at its front end with adownwardly-extending arm 126.

The front of the furnace is provided with bearings for alongitudinally-sliding dumpbar 127, which is provided in its front edgewith a series of notches 128 to register with the charging-doors 123.One end of the dump bar is connected by means of the pivoted rod 129with one arm 130 of a bell-crank lever, which is fulcrumed at 131, andthe other arm 132 of which serves as a handle by means of which it maybe manipulated to impart alongitudinally-sliding movement to'the dumpbar127. When the ingots are pushed or charged into the furnace, as will behereinafter described, the peels 124 are first placed in position, itbeing unnecessary, however, to slide the said peels into the furnaceuntil the arms or handles 126 engage the notches of the dump-bar. Whenthe ingots are afterward pushed into the furnace, they will carry thepeels with them until the handles 126 of said peels engage the notches128 in the dump-bar. It will thus be seen that by manipulating thebell-crank lever in such a manner as to slide the dump-bar in eitherdirection the peel will be tilted, thus rolling or tilting the ingotssupported thereon to either side of the chargingdoors of the furnace.

In the practical operation of my invention the car carrying theingot-molds filled with the molten metal is transported upon the tracks80 from the converting-mill and to the furnace. The car is so arrangedas to bring the molds or flasks into alignment with the charging-doorsof the furnace, and the cars 6 and 14, carrying the mast 13 and thepusher-cylinder with its attachments, are then manipulated to bring thesaid pushencylinder into alignment with one of the molds andfurnacedoors. The adjustment of the pushing mechanism may be veryquickly and-easily effected by means of the operating mechanism actuatedby the hydraulic cylinder 55. The moldcarrying frame of the car is thentilted by means of the worm and segmental rack to bring the molds into ahorizontal position with their upper ends toward the pusher-cylinder.Vhile the mold-carryiu g frameis being tilted to bring the molds in ahorizontal position the bottom plate of the molds is suffered to remainin contact with the lower ends of the latter, which are thereby closed,this being obviously necessary for the purpose of preventing the ingotsfrom dropping out of the molds by gravity. When the mold-carrying framehasbeen sufficiently tilted to bring the molds into a horizontalposition, or nearly so, the eccentric-rings 113 are operated by theirlevers or handles 112, which are released from under the studs 115 topermit the shafts 108,

having the supporting-hooks 110, to move outwardly in the slots 107,thereby releasing the bottom plate from the lower ends of the molds andpermitting the said bottom plate to swing down between the ends of thecar-frame. The lever-man or operator, who

is stationed upon the platform 39, now manipulates the pivotedgrappling-arms 34 by means of the lever 36 and handle 37 to cause thehooks 35 at the front or outer ends of said grappling-arms to engage thelugs or staples 102 at the upper ends of the holes or flasks 99. Thishaving been done, he next operates the clutch member 43 by means of thelever or handle 44: to force the clutch membereO and the rods 33, to thefront ends of which the grappling-rods are journaled, in a rearwarddirection against the tension of the springs 42, thus drawing the moldcontaining the ingot up into contact with the head 24 at the front endof the piston-rod 20 in the pusher-cylinder and serving to hold the saidmold securely While the ingot is being pushed out. The sliding movementof the mold just described is made possible by the presence of thevertical slots or port-holes 101 in the moldcarrying frame in which thesaid molds are supported by their flanges 100. The leverman nowmanipulates the operating rod or handle 79 of the valve 48 to so adjustsaid valve as to cause water under pressure to be admitted through thepipe 46 into the rear end ofrthe cylinder, thus causing the pistonrod tomove in a forward direction and to push the ingot out of the mold andinto the furnace through the charging-door with which it is inalignment. By reversing the valve 48 the piston is next caused torecede, and by manipulating the valve controlling the supply of waterinto the cylinder 58, the carriages supporting the pushing mechanism maynow be adjusted to place the piston into alignment with the next mold,after which the operation may be repeated. When all the ingots have beenpushed into the furnace, the mold-carrying frame is restored to itsnormal position and conveyed back intothe converting-mill to receive anew charge, while the pushing mechanism is held ready to operate uponthe next car-load of ingots that may arrive from the converting-mill.After all the furnacedoors have received their first charges thedump-bar 127 is manipulated to tilt the ingots into the spaces betweenthe chargingdoors of the furnace, and the peels may then be withdrawn,leaving the furnaces in readiness to receive the second charge. Afterhaving served the furnace on one side of the pushing mechanism thepushing-cylinder is reversed and made to serve the furnace on theopposite side. When the ingots have remained in the furnaces for asufficient length of time to raise them to the desired degree of heat,they may be drawn by using drawing-tongs of ordinary constructionprovided with hooks to engage the perforation 28 in the front end of thepiston-rod.

The head 24: of the piston-rod is meanwhile slid in a rearward directionupon the rod, so as toexpose the said perforation 28, this being done bysimply releasing the key 27 from engagement with the recess or openingin the piston-rod. By the use of the grappling-tongs the ingots aredrawn out upon a suitably-constructed car, which, inasmuch as it formsno part of my present invention, has not been illustrated in thedrawings, and upon which they may be conveyed along the tracks 80 to therolling-mill.

The advantages of my invention will be readily understood from theforegoing description,taken in connection with the drawings heretoannexed, by those skilled in the art to which it appertains. By theordinary method of manipulating ingots it has been customary to stripthe ingots from the molds in the converting-mill, where the molds areset for casting in a pit under the pouringladle. The process ofstripping the ingots has necessarily been slow and laborious, requiringthe assistance of numerous operators, the services of many of whom maybe dispensed with by my invention. In addition to this the steel, iskept in a far better condition than heretofore, owing to the fact thatit is at no time between the casting of the ingots and the charging ofthe ingots into the furnace exposed to the drafts of cold air, whichhave heretofore been instrumental in cracking and injuring the surfacesof the ingots, frequently entailing considerable loss, owing to theinferior quality of the product.

Another important advantage certain to be derived from my invention isthe facility with which the ingots may be handled in a highlyheatedstate, thereby effecting a considerable saving in the fuel necessary toraise them to the necessary degree of heat for rolling.

Other advantages might be mentioned;but it is thought that the foregoingwill be suificient to illustrate the superiority of my improved devicesfor handling ingots over the methods ordinarily employed.

In the detailed construction of the various parts of my invention I haveaimed not only at so constructing the various parts of the mechanism asto facilitate the actual handling of the ingots, but I have hadspecially in mind the difficulties to be overcome owing to the heavyweights to be handled and the highly-heated condition of the ingots.

It is obvious that all of the structural parts attained these objects bythe construction" and arrangement of parts herein described, andillustrated in the drawings hereto annexed; but I desire to have itdistinctly un derstood that I reserve the right to any changes andmodifications which may be resorted to without departing from the spiritof my invention.

I also desire it to be understood that While for various reasons Iconsider hydraulic pressure to be preferable as a motive and actuatingpower in connection with my invention I reserve the right to use anyother fluidpressure.
